Doesn't Gilmour also use scalloped
fretboards?
Not that I know of... Yngwie, Ritchie Blackmore... Steve Vai's Jem7MV (which I have with "Flo" designed Fernandes Sustainer) has the highest frets scalloped.
I've never really liked the feel. The only thing cool to me is that if you push down towards the neck, the pitch changes a bit, so you can develop your own signature style tremelo... like Vai does, which BTW, is mostly for looks. He does this circular thing (which I also do in the Pink Floyd vid) but it really can't be heard.
When I talked to Steve years ago at a NAMM show in Anaheim (long before his DLR days) he said it was mostly for looks. Steve is a very "Visual" and technical player combined.
His Astoria vid is insane with visuals.
